LAND, a citizen of the United States, residing in Montclair, county of Essex, and State of New Jersey, and CARROLL M. STANLEY, a 1n eWV ful Improvements in Filter-Casings, of which the following is a specification.

The present invention relates to certain new and useful improvements in pressure filter casings which comprise two complemental sections hingedly connected at one side thereof for opening and closing the casing, packing means being provided at the meeting edges of the sections to insure a liquid tight joint therebetween, one object of the invention being to provide novel means whereby the meeting edges of the hinged side of the casing sections can be positively adjusted relatively to each otherto maintain a liquidtight joint and to take up wear of the parts and packing.

A further object of the invention is to provide novel means whereby the degree of adjustment may be varied at different points along the hinged side of the casing so as to compensate. for irregularities due to the casting of the'casing sections, and to cause different pressures to be exerted in the packing at various points in the length of the casing as may be necessary to maintain a liquid tight joint.

Another object of the invention is to provide a novel construction of hinge specifically adapted for use with fluid tight casings formed in sections or having a hinged cover, whereby the hinge may be adjusted relatively to the casing sections which it connects so as to correct inaccuracies in the swinging relations of the parts which are due to improper hinge mounting.

For a full understanding of the invention reference is to be had to the following description and accompanying drawings in "which:

. Figure 1 is a side elevation of the hinged side of a sectional pressure filter casmg showing one embodiment of the present invention. i

Fig. 2 is an enlarged fragmentary trans.

verse vertical sectional view through the hinged side of the casing, showing one of the hinge members in side elevation.

Fig. 3 is a front elevation of the same.

Fig. 4 is a top plan view thereof.

Corresponding and like parts are referred to in the followin description and indicated in all the views 0% the drawing by the same reference characters.

For the purpose of illustration, the invention is shown in connection with a conventional typeof pressure filter casing, although it is to be understood that the invention is susceptible of use in connection with vacuum filters or practically all openable containers.

Specifically describing the present embodiment of the invention the numeral 1 designates the upper section, and 2 the lower section of a pressure filter casing A, which is of the type of casing comprising two com plemental sections hingedl'y connected at one side and secured together at the other side by suitable fastening means. One side of the upper section 1 of the casing is progitudinally of the casing and are provided with vertically disposed bores 4. The corresponding side of the lower section 2 of'the casing is provided with an equal number of similarly formed hinge lugs 5, which are provided with vertical bores 6 and are adapted to cooperate with the lugs 3 of the upper casing to receive hinge members B. which serve to hingedly connect the two sections 1 and 2. The lugs 3 and 5 are spaced from the meeting edges of the casing sections 1 and 2 to provide clearance for the 'hinge members B, and the lower face of each of the lugs 3 is undercut at 3 to provide a vertical flat shoulder 3*. A liquid tight joint is maintained between the meeting edges of the sections 1 and 2 by a packing strip 7 carried by one section and snugly engaging the other when the casing sections are moving together.

Each hinge member B comprises an eye bolt 8 having the eye 8 and threaded bolt 8 which is adapted to' be loosely received in the vertical bore 6 of the lug 5 of the lower casingsection-2. A castle nut 9 is threaded on the end of the bolt 8 and engages the tight joint between the sections.

castle nut to hold the nut on the said bolt..

A hinge bolt 11 is adapted to be loosely fitted in the vertical bore 4 of the lug 3 of the upper section 1 of the casing, said bolt being provided at its lower end with an enlarged bifurcated head 11", the arms of wh1ch are provided with transverse openin s 11 and straddle the eye 8 of the eye bo t 8 fitted in the corresponding lug 5 of the lower section 2, a hinge, pintle 12 being inserted through the openings 11 and eye 8 to connect the hinge bolts 8 and 11. The upper end of the bolt 11 is threaded and receives an adjusting nut 13, which engages the upper side of the lug 3, and a lock or jam nut 14;.

With this construction it will be seen that the tightening or loosening of either the adjusting nut 13 or castle nut 9 of any of the hinge members B will cause the sections 1 and 2 of the casing to be drawn together or separated so as to cause greater or less pressure on the packing strip 7 as may be desired. Further it will be noted that each hinge member B is independently adjustable so that the relation of the two sections 1 and 2 at practically any point in the length thereof can be varied to compensate for irregularities in the sections or to adjust improper hanging of the sections on the hinge members. Should the sections become warped, it will be obvious that by proper tighteningof some of the hinges and loosening of others the defect can be easily overcome. With reference to Fig. 3 of the drawing it will be noted that the enlarged head '11 of the hinge bolt 11 engages the fiat shoulder 13 so that the hinge bolts are prevented from turning while the nuts are being adjusted.

It is an important feature that the invention provides means for adjusting the hinged side of the sections of a pressure filter casing or other openable fluid pressure container so as to always maintain a liquid Further, the provision of a plurality of independently adjustable hinges allows varied adjustments of the casing sections at different points in their lengthswhich in many in stances will overcome the necessity of special work for providing proper fitting surfaces to the casing sections or special pack- Ilaving thus described our invention what We claim as new and desire to secure by Letters Patent is;
